Wyndham Timeshare: Is it worth the cost??

After so many hours sitting in their office, I finally signed up for the 68K point plan for $15K. They gave me 225K bonus pts, 5 RCI extra vacation cert. ($249 each). I think the bonus will qualify me to the VIP program for the 1st year. I signed the paper knowing that I have a 10 cooling period. I have since done some research and most seem to lean toward buying resale for a much cheaper price. How does purchasing a resale work?? And is it wise to do that instead of keeping my own contract??
